What is the difference between a laminating machine and a pre-coating machine?

Oct 25 2020

People who may not be familiar with laminating machine may not know it well, but as long as people who have been in contact with short-run printing, digital fast printing and other industries, it is impossible not to know. First of all, this kind of machine lamination is a one-time molding, and the consumables used have been coated with glue. When laminating, the glue is melted by heating, and then the film is adhered to the printed matter by pressure.

The pre-coating film machine is relatively cheap and simple to operate, and does not generate harmful gases during operation. It is a trend in the development of film coating. In today's society that is increasingly focusing on environmental protection, it has become the main coating technology in the domestic printing industry.

The pre-coated film machine consists of four main parts: pre-coated plastic film unwinding, automatic printing of printed matter, hot press zone compounding, and automatic winding, as well as mechanical transmission, pre-coated plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices. The process is a relatively special kind. In addition to the many advantages of the laminating process, it also increases the visibility of the product in the packaging. The colorful printing pattern is embedded with a curvy visual window, which not only makes The packaging is more exquisite, and at the same time it also plays a role in promoting and beautifying products and revealing the value of the products, becoming an effective means to realize and increase the value of products.

The difference between the filming principle of the pre-coating film machine and the general filming machine is:

1. It coats the adhesive on the surface of the film, then covers the film on the surface of the printed matter, and then presses it into a finished product.

2. The special advantage of the pre-coated film is that it can automatically spray powder and use the viscosity of the glue to dissolve the powder through heating to achieve automatic powder removal.
